90474818 ÷ 150 
The aim is to understand the frequency of 150 in 90474818.

Advancing to step 1:
If we divide 9 by 150, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 150

Let's proceed to step 2:
150 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 150

Advancing to step 3:
The number 150 fits into 904 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 900 away from 904, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 150

Let's proceed to step 4:
47 divided by 150 is 0 with a remainder of 47.
The next digit of our result is 0. 
Result so far: 60.0
Deduct 0 from 47 and we're left with 47.
Bring next digit (4) of the dividend behind the 47 and repeat the process: 474 / 150

Going ahead to step 5:
150 goes into 474 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 603.0
Deduct 450 from 474 and we're left with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 150

Let's proceed to step 6:
If we divide 248 by 150, we get 1 and a remainder of 98.
The number 1 becomes the next digit in our result. 
Result so far: 6031.0
Subtracting 150 from 248 leaves us with 98.
Take the next digit (1) from the dividend and append it to 98, then repeat: 981 / 150

Moving on to step 7:
When dividing 981 by 150, we get 6 with a remainder of 81.
The next digit of our result is 6. 
Result so far: 60316.0
If we subtract 900 from 981, we get 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 150

Going ahead to step 8:
150 can be fit into 818 5 times, resulting in a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 603165.0
Subtracting 750 from 818 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
If we divide 680 by 150, we get 4 and a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 603165.4
If we subtract 600 from 680, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
150 goes into 800 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 603165.45
Subtract 750 from 800 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
When dividing 500 by 150, we get 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 603165.453
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
If we divide 500 by 150, we get 3 and a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 603165.4533
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 603165.4533 and a remainder of 0.0005.
